The supposed importance of influentials derives from a plausible-sounding but largely untested theory called the "two-step flow of communication" : Information flows from the media to the influentials and from them to everyone else. Marketers have embraced the two-step flow because it suggests that if they can just find and influence the influentials, those select people will do most of the work for them. The theory also seems to explain the sudden and unexpected popularity of certain looks, brands, or neighborhoods. In many such cases, a cursory search for causes finds that some small group of people was wearing, promoting, or developing whatever it is before anyone else paid attention. Anecdotal evidence of this kind fits nicely with the idea that only certain special people can drive trends.
In their recent work, however, some researchers have come up with the finding that influentials have far less impact on social epidemics than is generally supposed. In fact, they don't seem to be required at all.
The researchers' argument stems from a simple observation about social influence: With the exception of a few celebrities like Oprah Winfrey—whose outsize presence is primarily a function of media, not interpersonal, influence—even the most influential members of a population simply don' t interact with that many others. Yet it is precisely these non-celebrity influentials who, according to the two-step-flow theory, are supposed to drive social epidemics, by influencing their friends and colleagues directly. For a social epidemic to occur, however, each person so affected must then influence his or her own acquaintances, who must in turn influence theirs, and so on; and just how many others pay attention to each of these people has little to do with the initial influential. If people in the network just two degrees removed from the initial influential prove resistant, for example, the cascade of change won't propagate very far or affect many people.
Building on the basic truth about interpersonal influence, the researchers studied the dynamics of social influence by conducting thousands of computer simulations of populations, manipulating a number of variables relating to people's ability to influence others and their tendency to be influenced. They found that the principal requirement for what is called "global cascades"—the widespread propagation of influence through networks—is the presence not of a few influentials but, rather, of a critical mass of easily influenced people.
By citing the book The Tipping Point, the author intends to ______.
A.analyze the consequences of social epidemics.
B.discuss influentials' function in spreading ideas.
C.exemplify people' s intuitive response to social epidemics.
D.describe the essential characteristics of influentials.
The question of GDP and its usefulness has annoyed policymakers for over half a century. Many argue that it is a flawed concept. It measures things that do not matter and misses things that do. By most recent measures, the UK&39;s GDP has been the envy of the Western world, with record low unemployment and high growth figures. If everything was going so well, then why did over 17 million people vote for Brexit, despite the warnings about what it could do to their country&39;s economic prospects?
A recent annual study of countries and their ability to convert growth into well-being sheds some light on that question. Across the 163 countries measured, the UK is one of the poorest performers in ensuring that economic growth is translated into meaningful improvements for its citizens. Rather than just focusing on GDP, over 40 different sets of criteria from health, education and civil society engagement have been measured to get a more rounded assessment of how countries are performing.
While all of these countries face their own challenges , there are a number of consistent themes . Yes , there has been a budding economic recovery since the 2008 global crash , but in key indicators in areas such as health and education , major economies have continued to decline . Yet this isn&39;t the case with all countries . Some relatively poor European countries have seen huge improvements across measures including civil society , income equality and the environment.
This is a lesson that rich countries can learn : When GDP is no longer regarded as the sole measure of a country&39;s success, the world looks very different .
So, what Kennedy was referring to was that while GDP has been the most common method for measuring the economic activity of nations , as a measure , it is no longer enough . It does not include important factors such as environmental quality or education outcomes - all things that contribute to a person&39;s sense of well-being.
The sharp hit to growth predicted around the world and in the UK could lead to a decline in the everyday services we depend on for our well-being and for growth . But policymakers who refocus efforts on improving well-being rather than simply worrying about GDP figures could avoid the forecasted doom and may even see progress .
Robert F. Kennedy is cited because he
A.praised the UK for its GDP.
B.identified GDP with happiness .
C.misinterpreted the role of GDP .
D.had a low opinion of GDP .
It can be inferred from Paragraph 2 that
A.the UK is reluctant to remold its economic pattern .
B.GDP as the measure of success is widely defied in the UK .
C.the UK will contribute less to the world economy .
D.policymakers in the UK are paying less attention to GDP .
Which of the following is true about the recent annual study ?
A.It is sponsored by 163 countries .
B.It excludes GDP as an indicator.
C.Its criteria are questionable .
D.Its results are enlightening .
In the last two paragraphs , the author suggests that
A.the UK is preparing for an economic boom .
B.high GDP foreshadows an economic decline .
C.it is essential to consider factors beyond GDP .
D.it requires caution to handle economic issues .
Which of the following is the best title for the text ?
A.High GDP But Inadequate Well-being , a UK Lesson
B.GDP Figures, a Window on Global Economic Health
C.Rebort F.Kennedy, a Terminator of GDP
D.Brexit, the UK"s Gateway to Well-being
